Recommended: An essay on volcanic eruption
Many people say that the earth is a living planet. Due to the fact that it is constantly changing, this statement holds true. The earth is always moving, both inside and out. Whether one thinks it is good that humans live on a planet that moves is good or not, everyone is affected. This is because when Mother Earth moves, people all across the world will feel it. There are many dangers that the Mother Earth and its geology present to human life. These things lay resting, waiting to be awakened. Things such as tornadoes, tsunamis, hurricanes, and even earthquakes are the very things that affect people in a way that changes them forever, whether it is by taking a life or destroying a home. All of these things are very destructive, but none like volcanoes. A volcano is a mountain or hill that has a crater through which lava, rock fragments, hot vapor, and gas are being or have been erupted from the earth's crust, as stated by Webster’s dictionary. They are formed when magma within the Earth's upper mantle works its way to the crust. This accumulates and forms a magma chamber. Over time this grows larger and a volcano is created. They hold scorching hot lava in their stomachs waiting for the right time to release it. Volcanoes are both incredibly dangerous and extremely destructive. There are literally countless volcanoes that are on earth; however, many of these volcanoes are not a threat because they are either dormant or extinct. Mt. Vesuvius is an active volcano; however, before discussing this volcano, the deliberation of the types of volcanoes must be talked about. There are three different types of erupting lives of volcanoes: extinct, dormant, and active. (Timothy Oleson)

... released. When it finally does release, it is volatile and is very explosive. Mount Vesuvius is a composite, or strato-volcano, and is the reason it had such a large explosion. Other famous composite volcanoes include the following: Mount Fuji in Japan, Mount Shasta and Lassen in California, Mount Hood in Oregon, Mount St. Helens and Mount Rainier in Washington, and Mt Pinatubo in the Philippines. (Jeffrey Kluger) The final type of volcanic composition is cinder cone volcanoes. Cinder cone volcanoes are different from shield and composite volcanoes because cinder cone volcanoes only grow to about a thousand feet, and they usually erupt from many openings. Famous cinder cones include Paricutin in Mexico and the one that is in the middle of Crater Lake. Volcanoes, no matter how they may look or what type it is, can be very devastating when it erupts. (Jeffrey Kluger)
Mount Saint Helens and Mount Vesuvius are volcanoes that have erupted they are both different and also the same here are some facts, similarities and differences of both the volcanoes.
Like most of the other volcanoes in the Cascade Range, St. Helens is a great cone of rubble, consisting of lava rock interlayered with ash, pumice and other deposits. Volcanic cones of this internal structure are called composite cones or stratovolcanoes. Mount St. Helens includes layers of basalt and andesite through which several domes of dacite lava have erupted. The largest of the dacite domes formed the previous summit; another formed Goat Rocks dome on the northern flank. These were destroyed in St. Helens' 1980 eruption.
What is a super volcano, what is a volcano? A volcano itself is a hill or mountain with vents to the crusts of the earth that let magma sit under or in the mountain. “A super volcano is any volcano capable of producing a volcanic eruption with an ejecta volume greater than 1,000 km3 (240 cu mi). This is thousands of times larger than normal volcanic eruptions. Super volcanos are on a much bigger scale than other volcanoes. Unlike composite volcanoes, with their steep sides, they are difficult to spot.” (Internet Geography, geography.learnontheinternet.co.uk) An average volcano in the world would just cause local damage, but this super volcano could end life on earth. Not just with the eruption but the ash would cause a volcanic winter blocking the sun to long and then even more the ash would choke everything out and collapse roofs. Yea Rainier would kill thousands of people, but Yellowstone would literally kill billions plus of people. In comparison, Rainier is a little fly and Yellowstone is a Griffin {The big eagle lion bird thing}. Yellowstone has the capability to erupt 1,000 times stronger than Rainier ever could.
Volcanoes. The naturally forming landforms that can look remarkably beautiful. Gentle slopes, or high rising heights with snow caps and greenery that seems to attract many tourists and sightseers around the world. These magnificent landforms can also cause major destruction and can produce forces that can explode, burn, and create a great deal of damage. Two of these extravagant wonders of the world is the Mount Saint Helens composite volcano in Washington, US, and the Mauna Loa shield volcano in Hawaii, US. These landforms have a eruption history of many colors. One has a great power in eruption, but another has a eruption that is quiet and gentle. In comparing these two volcanoes there are many likes, and dislikes, to consider. So the following
Myths and legends are everywhere. There are legends of people from long ago, myths of ancient Greeks. There are myths and legends of almost everything, including volcanoes. Myths of their creation, of why they erupt. Myths and legends of various gods controlling their own volcanoes. There is a story for almost every volcano. The amount of legends and myths concerning volcanoes is quite extensive, ranging from Hephaestus to Vulcan and everything in between. It's very interesting to know what people thought of volcanoes when the myths were made; myths about volcano are as captivating as other myths. Take Pele, one of the gods associated to volcanoes I'll be talking about, for example.
The Earth has a long history of volcanic activity. Currently, there are approximately 1,500 active volcanoes worldwide (USGS, 2014). Whether erupting on the Earth’s surface or deep in the ocean, volcanic activity can result in devastating natural disasters. A thorough background regarding volcanoes and their formation mechanisms, historical data, and damaging impact from previous eruptions is needed in order to understand the complicated science behind volcanoes.
Volcanoes class: class volcanoes common type of existence, which is formed in the center of the former types and its cones composed of rock debris material and lava flows directed by the volcano eruption, while restless. And the outcomes be coming out of the volcano eruptions during successive layers on each other, and some of them consisting of coarse material and another section of accurate materials, and between this and that interfere lava in a few strips of fish
Volcanoes have been around for many centuries and will continue to exist for many more to come. Many people have their ideas of what they believe volcanoes are. Most believe that it is basically a mountain that shoots out lava, destroying anything and everything nearby. This assumption is actually proven accurate. Volcanoes are considered one of the most dangerous natural disasters; they can erupt suddenly, destroying everything in its way. People tend to be so afraid of volcanoes that most of them don’t realize that there is one concept far more terrifying than just a volcano: a super volcano. Most have never even heard of them, but it has been proven that they are much worse than just normal volcanoes. Super volcanoes are known for being larger and more powerful than your typical volcano. According to National Geographic Magazine, a super volcano is a term used which describes explosions with exceptional violence and volume. The USGS states within the magazine article that super volcanoes are known for ejecting more than 1,000 cubic kilometers of pumice and ash. Super volcanoes are known to be approximately ten times larger and more powerful than an average volcano. This magazine also makes a known analogy that compares volcanoes and super volcanoes in a better perspective. It states that “volcanoes form mountains, super volcanoes erase them; Volcanoes kill plants and animals for miles around; super volcanoes threaten whole species with pure extinction by changing the climate across the entire planet. In order to assess the meaning of a super volcano, we must look at the different impacts it can have on the climate, how they are known for flaring up, the most current form of measurement, and even a little bit of history to compl...
I have never experienced a volcano erupting before because there are no volcanos where I live. A volcano is a hole in the earth’s surface where gasses, magma, pieces of rocks, and ashes explode from the earth. Mt St. Helens eruption included many details common to other eruptions that caused damage and destruction to property and lives affected the region has recovered in its aftermath.
Mount Vesuvius is a volcano near the Bay of Naples in Italy. The volcano is hundreds of thousands of years old. It has erupted over 50 times. The most known eruption took place in 79 A.D. In 79 A.D. Mount Vesuvius erupted onto the city of Pompeii. One witness wrote that the volcanic ash “poured across the land” and covered the city in “a darkness… like the black of closed and unlighted rooms.” When the volcano erupted it killed around 2,000 people. Even though the volcano covered the city in a thick layer of volcanic ash and lava, in 1748 a group of scientist found that after you dug through the layer of ash the majority of the city is still intact. This wasn’t the first major eruption the volcano has dished out. In 1780 B.C. it erupted and
Volcanos are extraordinary geographic things. In Sioux City Iowa we do not have any volcanos. In fact we do not have any in the United States, but we do have some in Hawaii. A volcano works by the lower density of the magma relative to the surrounding rocks cause it to rise. Bubbles start to form from the gas dissolved in the magma. The bubbles exit in the magma with great pressure. Pressure helps bring magma to the surface or over the surface. Sometimes with tremendous pressure. Nevado Del Ruiz Volcano Eruption 1985 included many details common to volcano eruptions and caused damage and destruction to property and lives that affected
The biggest volcanic eruption ever recorded by humans was the eruption of Mount Tambora on Sumbawa Island, Indonesia, in 1815 (livescience.com, pg. 1). It ranked “super colossal” on the Volcanic Explosivity Index, the second highest rating. The eruption resulted in a brief period of significant climate change that led to cases of extreme weather. Volcanoes can cause great devastation and harm to people, animals, environments. For instance, fast-moving lava, lahars, and other effects after an eruption can kill people and damage property on it’s way down. Above all, volcanic eruptions can even cause long term effects on the climate by making the world colder.
Volcanoes can be one of the most destructive forces on Earth. It is estimated that some
Global Warming One of the most substantial problems in the world today is global warming. This gradual warming of the earth is in occurrence at an extremely slow rate but it is happening. Many scientists believe that as human’s work and release greenhouse gases into the earth’s atmosphere, it can become dangerous for the long lasting life of humans and our environment. “Unless we take immediate action, the impacts of global warming will continue to intensify, grow ever more costly and damaging, and increasingly affect the entire planet - including you, your community, and your family” (“Global Warming Impacts”).
